How Does Refinancing Work? A Step-by-Step Guide

Refinancing means replacing your existing home loan with a new one either with a different lender, or a new deal with your current one. Done at the right time, it can lower your repayments, unlock equity, or fix a loan structure that no longer suits you.

The most common reasons people refinance

• A better rate especially if your current rate hasn't moved in line with the market, or you're paying a "loyalty tax" as a long-standing customer.
• Accessing equity to fund a renovation, an investment property deposit, or another major expense.
• Debt consolidation combining higher-interest debts into your home loan, ideally with a clear repayment plan.
• Changing loan structure moving from interest-only to principal & interest, adding an offset account, or switching between fixed and variable.

What the process actually involves

1. Compare your current position against the market your current rate, fees and loan structure versus what's realistically available to you now.
2. Check the numbers properly, not just the headline rate discharge fees, application fees, valuation costs, and Lenders Mortgage Insurance if your equity position has changed.
3. Apply and get conditionally approved with the new lender, which includes a fresh serviceability assessment refinancing isn't automatic just because you already have a mortgage.
4. Discharge and settle your new lender pays out the old loan and the new one begins.

The costs worth knowing about upfront

Refinancing isn't free. Depending on your situation, you may face a discharge fee from your current lender, an application or valuation fee with the new one, government registration fees, and if your loan-to-value ratio has increased potentially new Lenders Mortgage Insurance. A proper comparison weighs these costs against the savings, not just the rate difference.

When refinancing tends to make the most sense

Generally, refinancing is worth investigating when your rate is noticeably above current market offers, when your fixed rate period is ending, when your property has gained enough equity to remove LMI, or when your circumstances (income, structure, goals) have genuinely changed since you took out your current loan.
